Worth its weight in gold but won’t break your bank, the NT135T is set at a very affordable price, at around 45$, which is less than most cell phone cases. It is easy to charge too, just plug the PowerPak+ into any micro USB wall cable and wait til the green light is on.

Or that I would want an employer to have all the metrics I can extract, but for things like scouring the Enron emails for witnesses that would be sympathetic and willing to testify it could be amazing. For monitoring people with depression to make sure they aren’t getting worse it seems like it would be worth the privacy invasion.
